Understanding the Differences between LED, LCD and DLP Projectors & How they Work ? Guide to help u best suited for your application DLP, LCD, and LED Technology The technology used in projectors can generally be broken down into two types: transmissive or reflective. Because LCD projectors pass light through the LCD panels rather than bouncing it away, they are considered a transmissive medium. A DLP projector uses mirrors to direct the light in an image, so it is considered to be reflective. The third type of projector discussed, an LED projector, is named for the light source, not the type of projection technology. How DLP Projectors Work DLP projectors rely primarily on a DLP chip (called a digital micromirror device, or DMD), comprised of up to 2 million tiny mirrors, no wider than one-fifth the width of a human hair. Each mirror in this chip is capable of independent adjustment, moving toward or away from the light source to create a dark or light pixel. At this point, however, the image is in grayscale. Color is fed to the DMD by a beam of light that passes through a spinning color wheel before it reaches the chip. Each segment of the color wheel delivers one color. Basic color wheels support red, blue, and green, whereas more advanced color wheels support cyan, magenta, and yellow. While these chips can create up to 16.7 million colors, a DLP projector with a three-chip architecture can deliver up to 35 trillion colors. After color reaches the DMD, the image is fed through the lens and onto the projection screen. Advantages and Disadvantages to DLP Projectors DLP projectors require less maintenance than LCD projectors because they have a filter-free and sealed chip design, which means dust cannot settle on the chip and cause an image spot. They are effectively immune to color decay. Furthermore, they are not subject to the misalignment that can occur in LCD projectors with a three-panel design, which require each panel to be in perfect position to combine the image at the proper angle. However, DLP projectors with slower color wheels may give off a rainbow effect, which is when bright flashes of color appear on the screen, like rainbows. Also, although the chip is sealed, other components are not, so dust can settle on the color wheel and affect image quality. Another disadvantage may be the poor viewing range. Most DLP projectors are not readily compatible with zoom lenses or lens shift functions, which means they are best suited to smaller environments. This would likely not be the best choice for a large home theater projector. How LCD Projectors Work LCD projectors use the same liquid crystal displays that create the images in watches and other electronic devices. Specifically, most LCD projectors use 3 LCD technology, a patented system that combines three liquid crystal displays. An image is created in a multistep process, which begins with the light source providing a beam of white light. The white light is passed to three mirrors, called dichroic mirrors, that are specially shaped to reflect only a certain wavelength o flight. In this case, the mirrors reflect red, blue, and green wavelengths. Each beam of colored light is then fed to an LCD panel, which receives an electrical signal that tells it how to arrange the pixels in the display to create the image. All three LCD panels create the same image, but they have different hues because of the colored light passing through the panel. The images then combine in a prism, creating a single image with up to 16.7 million colors that is passed through the lens and projected onto the screen. Advantages and Disadvantages to LCD Projectors The technology in LCD projectors is more established and reliable than film projectors. However, they may still require maintenance, as pixels can burn out and dust particles can interfere with image quality. On the other hand, LCD projectors have no moving parts, as DLP projectors do, and they are generally less expensive than their DLP counterparts. They also support setups in larger rooms where a greater projection distance is needed, because they are compatible with zoom lenses and lens shifts. This makes them great for larger, at-home cinema projects, as long as there is a smooth projection surface available. How LED Projectors Work LED projectors are defined not by the display technology used, but the lighting. In fact, some DLP projectors with "solid-state illumination" technology are actually LED projectors. Another type of projector, the pico projector, commonly uses LED technology as well. Pico projectors are essentially handheld devices that use LCoS, or liquid crystal on silicon, which is similar to an LCD panel but reflective rather than transmissive. In these cases, the projector replaces the traditional lamp with longer-lasting and more efficient LEDs, colored in red, green, and blue. In DLP projectors, this also replaces the color wheel technology, instead letting the red, blue, and green LEDs shine directly on the DMD chip. The Advantages and Disadvantages to LED Projectors The LEDs in an LED projector have a much longer life than traditional projector lamps, rated at 10, 000 or even 20, 000 hours as opposed to 1, 000 hours to 5, 000 hours. As such, the LED light source is meant to last the entire life of the projector without ever needing to be replaced. This is a big advantage in multimedia setups because replacing traditional lamps can be a major expense in projector maintenance. There is no warm-up or cool-down time needed because the LEDs are much more energy-efficient than traditional light sources, and they are also much quieter. This reduces maintenance and operating costs. To Know which projector is best for you walk in at Av Integrators-Nashik or call Manoj @ 9422277128

PT-RZ370/RW330 PT-RZ370 3, 500 lm Full HD PT-RW330 3, 500 lm WXGA Approximately 20, 000 hours* of maintenance-free operation No need to replace the light source or air filter, providing a dramatic reduction in TCO. Long-lasting picture quality Excellent picture quality and brightness are maintained for a long time. Superb color reproduction Beautiful, vivid colors exceeding the levels of conventional projectors. Quick start, quick off The image appears almost instantly upon powering up, and there is no need for cooling after turning the power off. The power can be turned on immediately after being turned off, and it can be turned on/off as many times as you want. The PT-RZ370/RW330 features 3, 500 lumens of brightness. Rate of brightness deterioration in the LED/Laser-combined light source is extremely slow compared to lamp-based projectors. The SOLID SHINE drive uses a built-in sensor to constantly detect the light intensity of the light source and correct corresponding changes in white balance. This all helps to maintain excellent picture quality for a long period of time. Contrast is outstanding too, at 10, 000:1, and images are reproduced with a wide dynamic range. The PT-RZ370 also features a Full-HD (1, 920 x 1, 080) DLP™ chip, allowing highly detailed Full-HD images without resizing. In 1-chip DLP™ system projectors with conventional lamp, a color wheel is used for time-division multiplexing in a method where the human eye combines the result to achieve a full-color palette. In the PT-RZ370/RW330, this is done by on/off switching of the LED/Laser-combined light source. A unique Panasonic power supply circuit provides time-division multiplexing with ultrafast 30x drive.* The resulting, high-definition images exhibit virtually no color breaking.** Laser cooling is performed by releasing the heat to cooling fins, then cooling with a heat pipe cooling system. This suppresses temperature rises inside the projector and allows stable operation up to an ambient temperature of 45 °C (113 °F).* The use of this heat-pipe cooling system also achieves quiet operation of 29 dB, ** enabling viewers to concentrate on the presentation or on quiet movie scenes. The area between the LED/Laser to the DLP™ chip and prism is hermetically sealed to form an airtight structure for the optical block, the heart of the projector. This resists the effects of dust and other particles in the air, and enables use of the projector in a wide range of environments. Panasonic’s Daylight View Basic technology achieves sharp, easy-to-see images by clearly reproducing the details in dark image areas, which were previously difficult to see in brightly lit rooms. A built-in sensor measures the ambient light, and the Daylight View Basic function adjusts the halftone color and brightness level according to the surrounding illumination. This imaging mode is similar to DICOM part 14, which is a medical imaging standard. It reproduces X-ray images with remarkable clarity. Optimal color reproduction can be achieved by selecting this mode, compliant with ITU-R Recommendation BT.709, when images from an HDTV source are projected.
